     When it comes to friends, I desire those who will share my happiness, who possess wings of their own

and who will fly with me. I seek friends whose qualities illuminate (照亮) me and train me up for love. It is

for these people that I reserve the glowing hours, too good not to share.

     When I was in the eighth grade, I had a friend. We were shy and "too serious" about our studies when it

was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school,

but she would come to my house and we would sit down with pencils and paper, and one of us would say:"

Let's start with a train whistle today." We would sit quietly together and write separate poems or stories that

grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were

changing into social creatures and the stories and poems stopped.

     When I lived for a time in London, I had a friend, He was in despair (失望) and I was in despair. But our

friendship was based on the idea in each of us that we would be sorry later if we did not explore this great

city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent

things. We walked until our despairs disappeared and then we parted. We gave London to each other.

     For almost four years I have had remarkable friend whose imagination illuminates mine. We write long

letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the

other's dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most

interesting moments, I often think:"Yes, I must tell…."We have never met.

     It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than

the lifetime services of a psychologist (心理学家), who will only fill up the healing (愈合的) silence necessary

to those darkest moments in which I would rather be my own best friend.
